Research statement

Are you sure about your own judgments? Does it actually matter? I am interested in understanding the computation and roles of uncertainty in the brain. More specifically:(1) How does the brain estimate the uncertainty about its own judgments, and communicate this subjective confidence to others?(2) How does subjective confidence regulate learning? In particular, how does it regulate the inference of trends and regularities in dynamic environments?(3) How does subjective confidence regulate our decisions, such as the decision to explore certain options, or to seek out information by mere curiosity?

I combine several scales and approaches in order to understand how those three processes operate in the brain:

Computational level: the goal is to provide abstract, formal accounts of brain computations. I rely on Bayesian (and more generally probabilistic) inference to this end.

Macro- and meso- scales: the goal is to understand the coordination of brain-scale networks that supporting those computations (macro-level), and how the inferred variables and their uncertainty are encoded by large populations of neurons (meso-scale). I currently use fMRI and MEG to this end.

Molecules: I am interested in the role of neuromodulators in those computations, which actually bridge gaps between single neurons (of which they modulate the activity and plasticity) and large-scale networks (in which they are released simultaneously). I use fMRI, physiological measures (e.g. pupil size) and pharmacological interventions to address those questions
